[looks up from the small device in his hand] The machine monitors the levels of glucose in my blood and tells me a number. Anything between 90 and 180 is about normal so if the meter tells me a number lower than that, than I need more sugar and if the number is too high, then I need more insulin.

[the meter beeps and he reads the screen and turns it to show the other that the number is '76'] It's low so I need to drink some juice and get something to eat soon.
